Theinvention is directed to providingnovel sheetfolding mechanis n combined and ecooperating with verysimple, sturdy and highly efh'cient novelmeafns for optionallycollecting before folding off or not uncollected.

Objects and advantages of the invention The i invention finds wide ,and advantageous application in a type of; folder mechanism having a multi-way collecting cylin der. equipped with sheet-cutting means and of said cylinders. The novel folding mechanism controlling means of my invention maybe used, however, in other types of folding mechanism.

. With this arrangement of mechanism, the webs and sheets follow a; very short and simple path, which is the same for collecting and not collecting; there is clear, short and ff direct feed of the webs, with plentyof room at either sidefor any desired cross-association of webs there is no transferjfcif out sheets during collection; and very simple, fast and reliable means are. provided for selectively operating the folding devices to fold off either collected or. uncollected products. a v s 1 I The inventionflprovides rotary, bladeequipped foldinggmeansand actuating and controlling devices therefor which positively actuate the folding mechanismatthe folding off. locus, or as a desired alternative, positively prevent actuating of the folding mechanism, for either collected or u'ncollected folding off. The changefrom one function to theother is effected by a simplequarter turn' of the cam controlling the folding-off action, I

Referring I invention illustrated byway of example in the accompanying drawings,a running web supply is received from a, suitable source,

such as a fast rotary printing press-in which case the supply is-longitudinally folded, andnow to the embodiment forjfolding off the prodfolding devices for each sheet-carrying surusuallyassociated; The Websin such case are run over a former 1"(Fig. having pairs of forming and forwarding rolls 2'. v
